3-((1,1-Dioxidobenzo[d]isothiazol-3(2H)-ylidene)amino)propyl 2-chloro-2-phenylacetate (CAS 356088-58-9), molecular formula C18H17ClN2O4S and molecular weight 392.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((1,1-Dioxidobenzo[d]isothiazol-3(2H)-ylidene)amino)propyl 2-chloro-2-phenylacetate (C18H17ClN2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
